Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND [0001] The invention relates to computer communication techniques, and in particular, to mobile communication devices, systems, and methods for dynamic update of map data. [0002] An electronic map in a personal computer, a cell phone, or a personal digital assistant (PDA) is typically used for navigation. In addition to direction assistance, location-related information, such as points of interest (POI) is also desirable. [0003] Current electronic maps could provide more POI data. Even if a large quantity of POI data is provided, it may not meet user requirements. For example, given that one hundred thousand POI data records are distributed among Taiwan plane areas, which form one fifth of the 35,873 km2 total territory, only 14 POI data records per one km2 are available. SUMMARY [0004] Accordingly, mobile communication devices, systems, and methods for dynamic update of map data are provided. [0005] An exemplary embodiment of a mobile communication device for dynamic update of points of interest comprises a communication unit and a processor coupled thereto. The communication unit is capable of wireless communication within a range. The processor automatically determines if a server offering points of interest (POI) data exists in the range, and, if so, initiates a wireless communication channel with the server utilizing the communication unit and downloads the POI data therefrom. [0006] An exemplary embodiment of a mobile communication device for dynamic update of points of interest comprises a communication unit, a global positioning system (GPS) receiver, and a processor. The communication unit can initiate a wireless communication channel. Prior to transmitting a request for downloading POI data, the processor automatically retrieves coordinates of the mobile communication device from the GPS receiver, transmits the request comprising the coordinates through the wireless communication channel to a server, and downloads the POI data therefrom. [0007] An exemplary embodiment of a system for dynamic update of POI data comprises a mobile communication device and a server. The mobile communication device comprising an electronic map initiates a wireless communication channel with the server. The server determines current position of the mobile communication device, locates data of points of interest (POI) based on the position, and transmits the POI data to the mobile communication device through the wireless communication channel. The mobile communication device receives and integrates the POI data into the electronic map. DESCRIPTION OF THE DRAWINGS [0008] The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein: [0009] FIG. 1 is a block diagram of an exemplary embodiment of a communication system; [0010] FIG. 2 is a flowchart of an exemplary embodiment of dynamic POI data update; and [0011] FIG. 3 is a schematic diagram of a communication range of a mobile communication device. DETAILED DESCRIPTION [0012] Mobile communication devices, systems, and methods for dynamic update of map data are provided. Note that entities, steps, and configuration thereof described in the following are only examples and can be adjusted according to real requirements. [0013] In communication system 100 of FIG. 1, network 120 may be a network provided by a telecommunication service provider, a local area network (LAN), or the Internet. Mobile communication device 110 and server 130 initiate wireless communication channel 140 through network 120. They may directly initiate wireless communication channel 140 without utilizing network 120. For example, wireless communication channel 120 may conform to the specification of wireless LAN, Bluetooth, global system for mobile communications (GSM), general packet radio service (GPRS), wideband code division multiple access (WCDMA), CDMA2000, or Wi-Fi. [0014] Mobile communication device 110 is illustrated as a cell phone, but may alternatively comprise a personal digital assistant (PDA), a laptop, or a handheld device. [0015] Mobile communication device 110 comprises a global positioning system (GPS) receiver 6 which may be an integral component. Mobile communication device 110, however, may externally connect to a GPS receiver or may not utilize any GPS receiver. Components of mobile communication device 110 comprise processor 1, communication unit 2, storage device 3, input device 4, display 5, and GPS receiver 6. Processor 1 is coupled to the other components. Storage device 3 comprises an electronic map 31 and receiving rule 33. [0016] Communication system 100 executes a method for dynamic update of POI data. [0017] With reference to FIG. 2, communication unit 2 initiates wireless communication channel 140 (step S2). Processor 1 may receive from input device 4 a signal for transmitting a POI download request. When receiving the signal, processor 1 automatically retrieves position information indicating the current position of mobile communication device 110, such as current coordinates thereof received from GPS receiver 6 (step S4). Next, processor 1 transmits the POI download request comprising the position information (such as the coordinates) to server 130 through wireless communication channel 140 (step S6). Server 130 receives the position information (such as the coordinates) of mobile communication device 110 (step S8), locates POI data 131 based on the position information (step S10), and transmits POI data 131 to mobile communication device 110 through wireless communication channel 140 (step S12). Mobile communication device 110 downloads POI data 131 from server 130 through wireless communication channel 140 (step S14) and integrates POI data 131 to electronic map 31 (step S16). [0018] Techniques of GPS data transmission are well known in the art, thus, detailed description thereof is omitted. [0019] Although mobile communication device 110 actively issues its GPS coordinates for a POI download, server 130 may locate POI data based on other position information of mobile communication device 110 and actively or passively transmit the POI data thereto. [0020] With reference to FIG. 1, base station 142 is coupled to router 141 and network 120. For example, server 143 identifies the location of mobile communication device 110 by determining which base station covers mobile communication device 110, treats the located base station (base station 142) as the position information, and locates POI data according to the position information.
